Cold-chain compliant item storage cart system

ABSTRACT

Examples provide a system for cold-chain compliance of items on a smart storage cart. The smart storage cart includes a plurality of bins, a memory, a processor, and a data storage device storing a perpetual inventory (PI) of items on the cart. The cart automatically updates the PI in response to removal of items from the cart or addition of items to the cart. The smart storage cart activates bin restock indicators to identify bins for removal of items or addition of items to the cart. The cart monitors entrance into or exiting from geofence areas. A cold-chain compliance component calculates the smart storage cart&#39;s dwell-time outside temperature-controlled areas. The cart outputs an alert recommending return of the smart storage cart to a temperature-controlled area if the cart&#39;s dwell time approaches the maximum dwell-time and/or outputs an alert if the smart storage cart&#39;s dwell-time exceeds the maximum dwell-time.

BACKGROUND

Produce and other perishable items are typically shipped from a distribution center to a store on pallets in refrigerated trucks. When the pallets arrive at the store, store personnel manually break the pallet apart to separate out items from the pallet and move those items into bins or containers in a refrigerated area or cooler in a storage area until they are needed to restock a refrigerated display or freezer case. Cold-chain compliance specifies acceptable temperature ranges for cold-chain items. These temperature ranges are maintained by minimizing transport time outside refrigerated areas. When the items are needed for restocking temperature-displayed cases, those items are manually retrieved from the storage area and placed in a cart or basket for transport to the display area. Upon arrival at the correct display area, the store personnel use the retrieved items to manually restock coolers, refrigerated cases and/or freezer cases. This is frequently a long, time-consuming, inefficient and cumbersome process.

SUMMARY

Some examples provide a system for item storage cart cold-chain compliance. The system includes a smart storage cart. The smart storage cart includes a plurality of bins, a memory and at least one processor communicatively coupled to the memory. A first geofence area is located within a temperature-controlled storage area. A data storage device stores a perpetual inventory (PI) associated with a plurality of items associated with a plurality of item display areas in an item selection area. A restock manager component activates a bin restock indicator associated with a bin in the plurality of bins. The bin includes a plurality of instances of a selected item for restocking. A location monitor component detects the smart storage cart exiting the first geofence area and entering a second geofence area associated with a display area within the item selection area. The display area is assigned to the selected item. An update component, implemented on the at least one processor, that updates the PI on the data storage device to reflect removal of the plurality of instances of the selected item from the at least one bin and placement of the plurality of instance of the selected item onto the at least one display area assigned to the at least one item if the smart storage cart is removed from the second geofence area for a minimum threshold restocking time and then returned to the first geofence area within a maximum per-cart dwell time. A cold-chain compliance component outputs a first alert recommending return of the smart storage cart to the temperature-controlled storage area if a first per-cart dwell time-period after exiting the first geofence area expires. The cold-chain compliance component outputs a second alert identifying the plurality of instances of the selected item for disposal if a second per-cart dwell time-period after exiting the first geofence area expires prior to return of the smart item storage cart to the temperature-controlled storage area.

Other examples provide a system for cold-chain compliant item storage carts. The system includes a plurality of item storage carts. Each item storage cart in the plurality of item storage carts includes a plurality of item storage bins. The plurality of item storage carts includes a first item storage cart received at a first time and a second item storage cart received at a second time. A first computing device associated with an item selection area includes a memory and at least one processor communicatively coupled to the memory. An update component updates a PI associated with the item selection area to reflect receipt of the first plurality of items from the item distribution center if a first item storage cart in the plurality of item storage carts is detected entering a temperature-controlled area associated with the item selection area. The first item storage cart is detected via a cart location device coupled to the first item storage cart. A priority component analyzes an arrival time of each item storage cart in the plurality of item storage carts received at the item selection area. The priority component assigns a first-in first-out (FIFO) priority to each item storage cart in the plurality of item storage cart. A restock manager component activates a bin restock indicator associated with at least one bin on a highest priority cart in the plurality of carts containing a selected item. A bin indicator on the first item storage cart received prior to the second item storage cart is activated to select the first storage cart for restocking an item display area prior to the second storage cart based on the FIFO priority. A cold-chain compliance component outputs a first notification alert to a user device associated with at least one user via a network. The first notification alert includes an instruction to return the first item storage cart to a temperature-controlled storage area if a first per-cart dwell time-period after exiting the temperature-controlled storage area expires.

Still other examples provide a computer-implemented method for cold-chain compliant item storage on carts. A cart location device detects an item storage cart exiting a temperature-controlled area within an item selection area. A cold-chain compliance component on the item storage cart monitors an actual dwell-time occurring between an exit time when the item storage cart exits the temperature-controlled area and a return time when the item storage cart returns to the temperature-controlled area. If a first per-maximum dwell time expires prior to return of the item storage cart to the temperature-controlled area, an output device associated with the smart storage cart outputs a first alert recommending return of the item storage cart to the temperature-controlled area. If a second per-cart dwell time expires prior to return of the item storage cart to the temperature-controlled storage area, the output device outputs a second alert designating a set of items on the item storage cart for disposal. If the smart storage cart is removed from the temperature-controlled area for a minimum threshold restocking time and returned to the temperature-controlled area within a maximum per-cart dwell time, an update component updates the PI on the data storage device to reflect removal of a plurality of instances of a selected item from at least one bin on the smart storage cart and placement of the plurality of instance of the selected item onto at least one display area assigned to the selected item.

DETAILED DESCRIPTION

Referring to the figures, examples of the disclosure enable cold-chain compliant management of item storage carts. In some examples, a restock manager component activates a bin restock indicator on a bin of the item storage cart to indicate removal of at least a portion of the items from the bin for restocking an item display. The bin restock indicator indicates which items to remove from the cart, a quantity of the items to remove from the cart for restocking, and cold-chain compliance for each item on the cart. In this manner, the indicator efficiently provides relevant information to users in a timely manner when the information is needed.

In other examples, the restock manager component activates the bin restock indicator to indicate where a user should place items that are being loaded onto the cart. A bin restock indicator for a selected bin is activated to identify the selected bin in which items should be placed, a quantity of items to place on the bin, and/or cold-chain requirements associated with the item.

A location monitor component in some examples detects the smart storage cart exiting a first geofence area and entering a second geofence area associated with at least one display area within the item selection area assigned to the selected item. This location monitor identifies a time at which the cart leaves the first geofence area and enters the second geofence area for cold-chain compliance purposes. The amount of time between leaving a temperature-controlled first geofence area and returning to the first geofence area is the dwell-time for the items on the cart. The dwell-time is the amount of time a perishable item spends outside a refrigerated or freezer area. This provides more accurate dwell-time calculation for cold-chain compliance.

Other examples provide an update component that automatically updates the PI for an item storage cart to reflect removal of one or more items from the cart in response to removal for the cart from the second geofence area for a minimum threshold restocking time and returned to the first geofence area within a maximum per-cart dwell time. In this manner, the system automatically maintains a more accurate cart inventory and store inventory without user intervention.

A cold-chain compliance component is provided in other examples that outputs a first alert recommending return of the smart storage cart to a temperature-controlled (refrigerated) area if the cart's dwell time outside the temperature-controlled area exceeds a maximum dwell-time threshold for at least one item on the cart. This improves cold-chain compliance and reduces loss of items due to excessive time outside temperature-controlled areas.

Referring again to FIG. 1, an exemplary block diagram illustrates a system 100 for cold-chain compliant item storage carts. In the example of FIG. 1, a smart item storage cart 102 is a cart for storing cold-chain compliant items. Cold-chain compliant items are perishable items which require storage at a given temperature or temperature range to prevent spoilage. The items stored on the cart can include, without limitation, produce, meat, dairy items, frozen food items, or any other temperature-dependent items.

The smart item storage cart 102 includes an integrated computing device for executing computer-executable instructions 104 (e.g., as application programs, operating system functionality, or both) to implement the operations and functionality associated with the smart item storage cart 102. The smart item storage cart 102 includes at least one processor 106 and a memory 108. The smart item storage cart 102 can also include a user interface component 110.

The processor 106 includes any quantity of processing units and is programmed to execute the computer-executable instructions 104. The computer-executable instructions 104 can be performed by the processor 106 or by multiple processors within the smart item storage cart 102 or performed by a processor external to the smart item storage cart 102. In some examples, the processor 106 is programmed to execute instructions such as those illustrated in the figures (e.g., FIG. 21 and FIG. 22).

The smart item storage cart 102 further has one or more computer-readable media such as the memory 108. The memory 108 includes any quantity of media associated with or accessible by the processor 106. The memory 108 can be internal to the smart item storage cart 102 (as shown in FIG. 1), external to the smart item storage cart (not shown), or both (not shown).

The memory 108 stores data, such as one or more applications. The applications, when executed by the processor 106, operate to perform functionality on the smart item storage cart 102. The applications can communicate with counterpart applications or services such as web services accessible via a network 112. For example, the applications can represent downloaded client-side applications that correspond to server-side services executing in a cloud.

In other examples, the user interface component 110 includes a graphics card for displaying data to a user 116 and receiving data from the user. In some examples, the user interface component 110 outputs notification(s) 114 to the user 116. The output notification(s) 114 can include a return cart notification output to the user on condition a first per-cart wait time expires prior to removal of the smart storage cart 102 from a non-temperature-controlled area within the item selection area. In another example, the notification(s) 114 includes a disposal notification output to the user if a second per-cart wait time expires before the smart item storage cart 102 is removed from the non-temperature-controlled area within the item selection area. The notification(s) 114 in other examples includes a maintenance alert which is output by the user interface on condition the internal temperature of at least one bin in the smart item storage cart 102 is outside an acceptable threshold temperature range.

The user interface component 110 can also include computer-executable instructions (e.g., a driver) for operating the graphics card. Further, the user interface component 110 can include a display (e.g., a touch screen display or natural user interface) and/or computer-executable instructions (e.g., a driver) for operating the display. The user interface component 110 can also include one or more of the following to provide data to the user 116 or receive data from the user: speakers, a sound card, a camera, a microphone, a vibration motor, one or more accelerometers, a BLUETOOTH® brand communication module, global positioning system (GPS) hardware, and a photoreceptive light sensor.

The network 112 is implemented by one or more physical network components, such as, but without limitation, routers, switches, network interface cards (NICs), and other network devices. The network 112 can be any type of network for enabling communications with remote computing devices, such as, but not limited to, a local area network (LAN), a subnet, a wide area network (WAN), a wireless (Wi-Fi) network, or any other type of network. In this example, the network 112 is a WAN, such as the Internet. However, in other examples, the network 112 is local or private LAN.

In some examples, the system 100 optionally includes a communications interface component 118. The communications interface component 118 includes a network interface card and/or computer-executable instructions (e.g., a driver) for operating the network interface card. Communication between the smart item storage cart 102 and other devices, such as but not limited to a user device 120, a computing device 122, and/or a remote data storage device 124, can occur using any protocol or mechanism over any wired or wireless connection. In some examples, the communications interface component 118 is operable with short range communication technologies such as by using near-field communication (NFC) tags.

In some examples, the communications interface component 118 is configured to output a return cart notification to the user device 120. The return cart notification can be output if a per-cart wait time expires before the user removes the smart storage cart 102 from a non-temperature-controlled geofence area within the item selection area.

The user device 120 represents any device executing computer-executable instructions. The user device 120 can be implemented as a mobile computing device, such as, but not limited to, a wearable computing device, a mobile telephone, laptop, tablet, computing pad, netbook, gaming device, and/or any other portable device. The user device 120 includes at least one processor and a memory.

The user device 120 can also include a user interface component.

The computing device 122 is a device for executing computer-executable instructions. The computing device 122 can be a desktop computer, a server, or any other type of computing device. The computing device 122 in some non-limiting examples is executing a cart controller 124 for remotely controlling one or more functions of the smart item storage cart 102, such as, but not limited to, sensor devices, a navigation system, a braking system, an alert system, an output device or any other portion of the smart item storage cart.

The system 100 can optionally include a data storage device 126 for storing data, such as, but not limited to an inventory 128 of the contents of the smart item storage cart 102 and/or threshold(s) 130. The data storage device 126 can include one or more different types of data storage devices, such as, for example, one or more rotating disks drives, one or more solid state drives (SSDs), and/or any other type of data storage device. The data storage device 126 in some non-limiting examples includes a redundant array of independent disks (RAID) array. In other examples, the data storage device 126 includes a database.

The data storage device 126 in this example is included within the smart item storage cart 102 or associated with the smart item storage cart 102. In other examples, the system 100 includes a remote data storage device 124 accessed by the smart item storage cart via the network 112. The remote data storage device 124 can include a data storage device associated with a store, a data storage in a remote data center, or a cloud storage. The remote data storage device 124 in this non-limiting example includes a store perpetual inventory (PI) 132.

The memory 108 in some examples stores one or more computer-executable components. Exemplary components include a cart controller component 134. The cart controller component 134 detects an item storage cart exiting a temperature-controlled area. The cart controller component 134 monitors a dwell-time for the cart. The dwell-time is the amount of time occurring after the smart item storage cart 102 exits the temperature-controlled area and a return time when the smart item storage cart 102 returns to the temperature-controlled area. A bin indicator 136 outputs an alert 138 if the dwell-time exceeds a per-cart maximum dwell-time before the cart returns to a temperature-controlled area. The alert 138 notifies the user 116 to return the smart item storage cart to the temperature-controlled area.

In other examples, the cart controller component 134 updates the inventory 128 of the smart item storage cart to reflect removal of one or more instances a selected item from at least one bin on the smart storage cart if the smart storage cart is removed from the temperature-controlled area for a minimum threshold restocking time and then returned to the temperature-controlled area within the per-cart maximum dwell-time.

FIG. 2 is an exemplary block diagram illustrating an item selection area 200. The item selection area 200 includes a geo-fence area 202 within a temperature-controlled storage area 204 and a plurality of item storage carts. The temperature-controlled storage area 204 can include a refrigerated area or a freezer area in a backroom storage area. An item storage cart 208 in the plurality of item storage carts 206 is a cart for storing items, such as, but not limited to, the smart item storage cart 102 in FIG. 1.

The item storage cart 208 self-navigates out of the first geofence area 202 and enters a second geofence area 210. The item storage cart 208 waits in the second geofence area 210 until a user 212 moves the item storage cart 208 to one or more item display(s) 214 within a temperature-controlled storage area 216 on a sales floor area within the item selection area 200. The user 212 removes one or more item(s) 218 from the item storage cart 208 and places the item(s) 218 on the one or more item display(s) 214. The display(s) 214 can include, without limitation, a refrigerated case, a freezer case, a side-counter, a produce display, an end-cap display, shelves, or any other item display.

The item storage cart 208 updates a PI 220 value 222 representing inventory of the item(s) 218 within the item selection area 200. The PI 220 can be stored on a data storage device 126 located within the item selection area. The PI 220 can also be maintained on a storage located remotely from the item selection area 200.

FIG. 8 is an exemplary schematic diagram illustrating an empty item storage cart 800 including a plurality of item storage bins. The empty item storage cart 800 includes a first side member 802 including three vertical compartments enclosing three item storage bins arranged in a vertically stacked configuration. In this example, the side member 802 includes bin 804, 806, and 808. The bins 804, 806 and 808 are facing outward at the first side member. However, the sides of the bins 804, 806 and 808 can be seen at the second side member 804.

The second side member 804 includes three vertical compartments enclosing three item storage bins arranged in the vertically stacked configuration. The three item storage bins in this example include item storage bins 812, 814 and 816 facing outward at the second side member 804.

The third side member (not shown) also includes three vertical compartments enclosing three item storage bins arranged in the vertically stacked configuration. The fourth side member of the cart (not shown) includes three more vertical compartments enclosing three item storage bins arranged in the vertically stacked configuration.

The empty item storage cart 800 in this example includes a forklift channel 818 and another forklift channel 820. The forklift channels 818 and 820 enable a forklift to lift the fully stocked item storage cart onto a transportation vehicle, such as a truck or ship and/or remove the item storage cart off a transportation vehicle.

Although the cart in this example includes three item storage bins on each side of the cart in a single vertical column, the examples are not limited to this configuration of bins. The item storage bins can be arranged on the cart in any configuration using any number of bins on any number of levels of the cart. For example, there can be four item storage bins on each side of the cart. In still other examples, two bins are located side by side on a single level of the cart. In other examples, the cart includes two levels of item storage bins instead of three levels of item storage bins, etc. In still another example, the cart include four levels of item storage bins.

In one non-limiting example, the item storage cart 800 is constructed of welded steel with one-inch square tubing. The top member can be sixteen-gauge steel, the runners can be fourteen-gauge steel, and the cater plates are three-sixteenths inch steel. The set of wheels are five inches by one and one-fourth inch swivel casters with directional locks. In some examples, the item storage cart has a storage weight capacity in a range from one thousand to eleven hundred pounds. In one example, the weight limit is one thousand fifty pounds. The forklift channels in another example are implemented as fourteen-gauge fork channels.

FIG. 9 is an exemplary cross-section view of an item storage cart 900. A central cavity 902 encloses the memory, processor, wires, power source, and/or a data storage device. The item storage cart 900 includes compartments 904, 906, 908, and 910 for holding item storage bins. Each item storage bin rests on a runner, such as the runners 912, 914, and 916. In this example, an item storage bin in the compartment 904 rests on the runners 914 and 916.

FIG. 10 is an exemplary side view of an item storage cart 1000. The item storage cart 1000 includes a lip 1002 along the top member of the cart. In this example, an item storage bin 1004 is placed on a top(first) level, an item storage bin 1006 is placed on the middle (second) level, and an item storage bin 1006 I spaced on the bottom (third) level of the cart. Each item storage bin includes a bin indicator device. The item storage bin 1008 has a bin indicator 1010 located just below the bin. The item storage bin 1006 includes a bin indicator 1012, and the item storage bin 1004 includes a bin indicator device 1016.

In one example, if the user is assigned to restock a side-counter using apples from the item storage bin 1006, the bin indicator 1012 lights up and/or displays an indicator identifying the contents of bin 1006 for removal. The indicator can include a symbol, letter, number, word, sentence, instruction, icon, or other indicator informing the user as to which items to remove from the cart for restocking.

In another example, if the user is assigned to restock a display with half the oranges in the item storage bin 1008 and leave the other half of the oranges in the bin 1008, the bin indicator 1010 outputs an indicator identifying half the contents of the bin 1008 for removal. In this example, the bin indicator lights up a half-circle, provide a fifty percent symbol on a small LED screen, output the word half, or other wise provide an indicator instructing the user to remove only a portion of the contents of the bin.

In one example, the indicator is an LED display which scrolls text, shows pictures, and/or outputs colors. The LED display in one example is one inch in height and two inches long. In another example, the LED display is one inch in length and three inches long.

In one example, the length of a side of an item storage bin is twenty-four inches long. In another non-limiting example, the width of the item storage bin is sixteen and one-half inches wide. In yet another non-limiting example, a height of an item storage bin is fourteen inches high.

FIG. 11 is an exemplary bottom view of an item storage cart 1100. The item storage cart 1100 includes the wheels 1102, 1104, 1106, and 1108. Each wheel is attached via a plate, such as the plate 1110. The cart can include a handle 1112. Each wheel caster in this non-limiting example is in a locked orientation for nested stacking of carts.

In one non-limiting example, the item storage cart's base member has an overall length of forty-four inches and an overall width of forty-one inches. The item storage cart in another example has an overall height of fifty-eight inches. However, the examples are not limited to these examples. In other examples, the item storage cart can have different measurements. For example, an item storage cart can have a length of forty-two inches, a width of forty inches, and a height of sixty inches.

FIG. 12 is an exemplary side view of stacked item storage carts 1200. In this non-limiting example, an item storage cart 1202 is stacked on top of another item storage cart 1204 for transportation. The carts are stacked with the wheels locked in an outward configuration to prevent the wheels from rolling/turning. The lip on the bottom cart 1204 prevents the top cart 1202 from shifting or sliding off. Both carts are wrapped in sheets of plastic shrink wrap or otherwise secured together prior to shipping.

FIG. 13 is an exemplary block diagram illustrating a bin indicator device 1300. The bin indicator device 1300 can provide a partial indicator activation 1302 indicating only a portion of the contents of an item storage bin for removal from the bin. The bin indicator device 1300 can provide a full indicator activation 1304 indicating all the contents of the bin for removal or indicating the entire bin is to be filled with instances of a selected item.

The bin indicator device 1300 can output/display a selected item identifier 1306 identifying the items inside the item storage bin or identifying the items that are to be placed inside the item storage bin. A bin identifier 1308 is a unique identifier associated with each bin. The bin identifier 1308 can include a serial number, a barcode, a matrix barcode, a QR code, a UPC code, an RFID tag, or any other type of identifier. The bin identifier 1308 can be displayed indicating which bin should be filled. For example, if a bin is identified as bin number 2A, a bin indicator displaying the word “apple” and the bin identifier “2A”, indicates the user is instructed to fill the bin “2A” with apples.

The bin indicator device 1300 in some examples includes a quantity 1310 for removal and/or a quantity 1312 of instances of the item to remain in a given item storage bin. The bin indicator device 1300 can also output a current temperature 1314 inside a given item storage bin, a cold-chain compliance indicator 1316 indicating whether the items in a given bin are cold-chain compliant, a return time remaining 1318 indicating how much time remains before the item storage cart must be returned to a temperature-controlled area, and/or a current dwell-time 1320 indicating how long the cart has been outside the temperature-controlled area.

The bin indicator device 1300 in other examples provides a countdown cart return timer 1322 providing a countdown timer indicating when the cart should be returned to the temperature-controlled area. For example, if the threshold dwell-time for the item storage cart is five minutes away, the countdown cart return timer 1322 provides a countdown from five minutes down to zero. The countdown cart return timer 132 informs the user stocking displays with items obtained from the cart how much time remains to complete the restocking task.

A warning 1324 can be given when the cart's dwell-time is approaching the maximum dwell-time for items on the cart. For example, if the cart's dwell-time is ten minutes away from reaching the maximum dwell-time, the bin indicator device 1300 can output a ten-minute warning, provide an audible alarm, flash a warning light, a text warning, output a notification to a user device, or any other warning. An audible alarm can include a beeping, ringing, verbal recorded warning, or any other sound. A warning light can include a red light, a yellow light, a flashing light, etc. A text warning can include a display of the words “ten-minute warning”, “10 minutes”, “return cart”, or any other warning text. If the cart remains outside the temperature-controlled area for too long (past threshold maximum dwell-time), a spoilage alert 1326 can be provided by the bin indicator device 1300.

FIG. 14 is an exemplary block diagram illustrating bin indicator devices on an item storage cart 1400. In this example, two item storage bins are side-by-side on a single level of the cart. Larger item storage bins such as these can accommodate larger items, such as, but not limited to, melons, pineapples, or other large items. Each item storage bin includes a bin indicator device. In this example, item storage bin 1402 is associated with bin indicator device 1404. Likewise, item storage bin 1406 is associated with bin indicator device 1408.

FIG. 15 is an exemplary block diagram illustrating bin indicator device lights. In this example, a fully lit indicator light identifies an item storage bin whose contents are to be completely emptied to fully stock a display/side-counter. The light is fully turned on if a full case is to be stocked.

The indicator light 1504 is half-lit indicating only half the contents of a given item storage bin are to be removed and utilized for restocking the display. In some examples, the indicator is half lit if only half a display case is to be stocked. The turned off (de-activated) bin indicator light indicates the item storage bin is empty/all contents of the bin have been utilized to stock the display(s).

In some examples, the system assumes that items in a selected bin that has a fully lit indicator have all been removed if the cart has been moved to the sales floor. In other words, once a cart is removed to the salesfloor, the system assumes any items in bins with a fully lit indicator have been utilized to stock the display(s) on the salesfloor. When the cart returns to the storage area, the system automatically turns the light off and updates the cart inventory to indicate the items associated with the selected bin have been added to the display(s)/removed from the cart.

FIG. 16 is an exemplary block diagram illustrating a set of sensor devices 519 on an item storage cart. The set of sensor devices 519 in some examples includes a set of one or more temperature sensors 104 generate temperature data 1604 associated with an internal temperature 1606 of the item storage cart.

A set of one or more weight sensors 1608 generates weight data 1610 associated with items on the item storage cart. In some examples, the weight data 1610 indicates a per-bin weight for each item storage bin. A set of one or more motion sensors 1614 can be included. The set of motion sensors 1614 generate motion data 1616 associated with movement of the item storage cart and/or motion of each item storage bin on the cart.

The set of sensors can optionally include a set of one or more pressure sensors 1126. A pressure sensor in the set of pressure sensors 1126 generates pressure sensor data 1620 associated with items within each item storage bin and/or items within the item storage bin.

The set of sensor devices 519 can include a set of image capture devices 1622 configured to generate image data 1624 associated with bin content image(s) 1626 of items (contents) in each item storage bin on the cart. The image data 1624 in some examples is utilized to verify the contents of each item storage bin.

In still other examples, the set of sensor devices 519 includes optical sensors, heat sensors, off-gassing sensors for detecting item spoilage, etc.

FIG. 17 is an exemplary block diagram illustrating a cart controller component 134. A restock manager component 1702 activates 1704 a bin restock indicator associated with at least one bin in a plurality of bins on an item storage cart indicating that instances of a selected item in the bin are ready to be used for stocking a display. In some examples, the restock manager component 1702 partially activates the bin indicator to indicate a portion of the instances of a selected item in a given item storage bin for removal from the at least one bin and placement on the item display area assigned to the selected item, wherein a portion of the plurality of items in the at least one bin remain in the at least one bin.

A location monitor component 1706 monitors a location 1708 of the smart storage cart within an item selection area. The location monitor component 1706 in some examples detects the smart storage cart exiting a first geofence area and entering a second geofence area associated with at least one display area within the item selection area assigned to the at least one item. A geofence locator 1710 can be utilized to detect the boundaries of a geofence area. The location monitor 1706 monitors an amount of time or time-period 1712 during which the cart is outside a geofence area, as well as the time-period 1712 the cart is inside a geofence area.

The restock manager component 1702 de-activates 1714 the bin indicator if the time-period 1712 between removal of the smart storage cart form the second geofence area and return of the smart storage cart to the second geofence area exceeds the minimum threshold restocking time. The minimum threshold restocking time is an estimated amount of time required for a user to remove the items from the selected item storage bin and restock one or more item display areas.

An update component 1718 performs an update 1720 of the PI 1722 for the selected item 1724 in an inventory record 1726 on the data storage device. The update 1720 reflects removal of the instances of the selected item from the bin and placement of the instance of the selected item onto the item display areas assigned to the item if the smart storage cart is removed from the second geofence area for a minimum threshold restocking time 1728 and returned to the first geofence area within a maximum dwell time threshold 1730 for the cart. In some examples, the update component 1718 updates the inventory of items inventory record 1726 on the data storage device in response to addition of at least one item to the at least one item storage bin or removal of at least one item from the at least one item storage bin.

A cold-chain compliance component 1732 outputs a return cart alert 1734 recommending return of the smart storage cart to the temperature-controlled storage area on condition a first per-cart dwell-time 1736 after exiting the first geofence area expires. The cold-chain compliance component 1732 outputs a cold-chain alert 1738 (second alert) indicating items for disposal if a second per-cart dwell-time 1740 after exiting the first geofence area expires prior to return of the smart item storage cart to the temperature-controlled storage area.

FIG. 18 is an exemplary block diagram illustrating a cart controller component 134 for cold-chain compliance. A cold-chain compliance component 1732 analyzes a per-cart dwell time 1804 and internal temperature 1806 of a given item storage cart using an acceptable temperature threshold range 1808 and the maximum threshold dwell-time customized for the items on the item storage cart. If the temperature falls outside the acceptable threshold temperature range and/or the dwell-time exceeds the maximum dwell-time threshold, the cold-chain compliance component 1732 triggers a notification component 1810 to send a notification or warning to at least one user. In other words, the dwell-time threshold is used to determine when to send a warning or other notification to the user associated with an item's cold-chain compliance.

In some examples, the notification component 1810 outputs a return cart notification 1812 to the user and/or to a user device associated with the user. The return cart notification 1812 in some examples includes a remaining time 1811 until a maximum threshold dwell-time is reached.

In some examples, the return cart notification 1812 instructs the user to return of the smart storage cart to the temperature-controlled storage area. The return cart notification can be sent if the per-cart wait time expires prior to removal of the smart storage cart from the second geofence area, if the maximum threshold dwell-time is approaching (within a predetermined amount of time prior to reaching the maximum threshold dwell-time), or if sensor data indicates all items for restocking have been removed from the cart.

The notification component 1810 in other examples outputs a disposal notification 1814 instructing the user to dispose of one or more instances of the selected item associated with the at least one bin if a maximum per-cart dwell time-period after exiting the first geofence area expires prior to return of the smart item storage cart to the temperature-controlled storage area.

An analysis component 1816 analyzes sensor data 1818 generated by a set of sensor devices. The sensor data 1818 is analyzes using item recognition analytics to monitor the contents of each item storage bin and/or monitor an internal temperature associated with the contents of the item storage cart. The sensor data 1818 is analyzed to verify the proper quantity of instances of the selected item have been removed from the at least one bin upon return of the smart storage cart to the first geofence area. In still other examples, the sensor data is analyzed to detect spoilage of items within the item storage cart.

In still other examples, the notification component 1810 outputs a maintenance notification 1822 to a user device associated with a user indicating a maintenance issue associated with the smart storage cart if the cart controller component 134 stops receiving sensor data 1818 from the set of sensor devices. In this manner, the cart monitors its own maintenance needs. In other examples, the maintenance notification 1822 is sent if the internal temperature is outside an acceptable threshold temperature range.

FIG. 19 is an exemplary block diagram illustrating a smart item storage cart 102 including a navigation system 1902. The navigation system 1902 enables the smart item storage cart to move autonomously (self-propelled) around a DC or an item selection area without user intervention. The navigation system 1902 can include a GPS 1904, image analysis 1906 of sensor data, including image data received from cameras mounted on the cart, geo-fence detection 1910, and/or cart location 1912 via cart location devices.

The cold-chain compliance component 1732 triggers 1916 automatic return 1918 of the smart storage cart to the temperature-controlled storage area via the navigation system 1902 without user assistance. The return 1918 of the cart can be triggered if the per-cart dwell-time 1920 expires while the smart item storage cart is located outside the temperature-controlled storage area. In other examples, cart return 1918 is triggered if the return cart threshold time 1922 is reached prior to return of the cart to the temperature-controlled area.

In another example, the navigation system 1902 automatically leaves a first geofence area in a storage area and goes to a second geofence area in proximity to an item display area in response to designation of instances of a selected item for restocking the item display. If the cart is removed from the second geofence area and then returned to the second geofence area by a user after a minimum restock time, the system assumes the instances of the item have been removed from the cart and used to restock the item display. The smart item storage cart then returns autonomously to the first geofence area when restocking is complete.

In another example, when the smart item storage cart arrives in the second geofence area, the self-propelled smart item storage cart waits within the second geofence area for the per-cart wait time 1924. However, if the cart is not removed from the second geofence area within a per-cart wait time 1924, the item storage cart automatically leaves the second geofence area and autonomously returns to the first geofence area to ensure cold-chain compliance for items on the cart upon expiration of the per-cart wait time.

FIG. 20 is an exemplary block diagram illustrating a priority component 2000 for prioritizing item storage cart re-stock scheduling. The priority component 2000 analyzes cart arrival times 2002 for each cart in a plurality of item storage carts 320. The plurality of item storage carts 320 includes one or more carts, such as, but not limited to, the smart item storage cart 102 in FIG. 1.

The arrival time is a time at which an item storage cart arrives at an item selection area, such as a truck delivery date and time. In this example, the cart 2006 has a first arrival time 2008 and another cart 2010 has a different arrival time 2012. The priority component 2000 assigns a first-in first-out (FIFO) priority to each smart storage cart.

For example, an item storage cart 2014 can have a priority 2016 and another item storage cart 2018 can have a highest priority 2020 if the item storage cart 2018 arrived before the item storage cart 2014. Thus, highest priority item storage cart 2018 is selected to restock item displays prior to the lower priority item storage cart 2014. In some examples, a bin indicator on the item storage cart 2018 including instances 2024 of a selected item 2020 received prior to the item storage cart 2014 also storing instances of the same selected item 2022 is activated to select the first storage cart 2018 for restocking an item display area prior to the item storage cart 2014 based on the FIFO priority.

FIG. 21 is an exemplary flow chart illustrating operation of the computing device to output cold-chain compliant notifications associated with an item storage cart. The process shown in FIG. 21 can be performed by a cart controller component, executing on a smart item storage cart, such as the smart item storage cart 102 in FIG. 1.

The process begins by detecting a cart leaving a temperature-controlled geofence area 2102. The cart controller component calculates current dwell-time for the cart at 2104. The cart controller component determines if the current dwell-time exceeds a first threshold at 2106. If yes, the cart controller component outputs a warning notification at 2108. The cart controller component determines if the dwell-time exceeds a second threshold at 2110. If yes, the cart controller component outputs a second notification at 2112. The second notification in some examples is an item disposal/spoilage notification. The process terminates thereafter.

If the dwell-time exceeds the first threshold at 2106, the cart controller component determines if the cart is returned to the temperature-controlled area at 2114. If no, the process returns to 2106. The cart controller component iteratively executes operations 2106 through 2114 until the cart is returned to the temperature-controlled area. If the cart is returned to the temperature-controlled area at 2114, the process terminates thereafter.

While the operations illustrated in FIG. 22 are performed by a computing device integrated into a smart item storage cart, aspects of the disclosure contemplate performance of the operations by other entities. For example, a cloud service can perform one or more of the operations.

FIG. 22 is an exemplary flow chart illustrating operation of the computing device to manage cold-chain compliance and inventory updates associated with an item storage cart. The process shown in FIG. 21 can be performed by a cart controller component, executing on a smart item storage cart, such as the smart item storage cart 102 in FIG. 1.

The process begins by detecting a cart arrival into a geofence area associated with an item display at 2202. The cart controller component determines if the cart is removed from the geofence area at 2204. If yes, the cart controller component determines if the cart is returned to the geofence area at 2206. If yes, the cart controller component calculates a removal time at 2208. The removal time is the amount of time between removal of the cart from the geofence area and return of the cart back to the geofence area.

The cart controller component determines if the cart removal time exceeds a minimum restock time at 2210. If yes, the cart controller component updates a PI value for the cart at 2212. The process terminates thereafter.

If the cart is not removed from the geofence area, the cart controller component determines if the cart has remained in the geofence area for a maximum (MAX) wait time at 2214. If yes, the cart controller component triggers autonomous cart returns to a temperature-controlled area at 2216. The process terminates thereafter.

While the operations illustrated in FIG. 22 are performed by a computing device integrated into a smart item storage cart, aspects of the disclosure contemplate performance of the operations by other entities. For example, a cloud service can perform one or more of the operations.

Additional Examples

Some examples provide a cart to be used in a store which accommodates bins for storing, stocking and moving items, such as produce. The store system communicates with the cart to update orders and inventory records. This enables communication of perpetual inventory (PI) information and pick logic. The software/system enable the store to locate the cart in the store and determine the ability of the cart for stocking purposes. The cart includes a robotic propulsion system to move the cart under its own power to the proper location in the store for DC for stocking. The cart with bins include a light indicator, a digital readout, and/or an LED display for indicating the fill status of the cart. The indicator illuminates based on the amount of the cart that is currently filled. If a full display case needs to be stocked, a full light illuminates on the cart. If half a display case needs to be filled, half of the lights are illuminated on the cart. The carts optionally include an optical sensor, a weight sensor and an off-gassing sensor. These sensors are used to indicate if the cart is empty or to detect spoilage of the items inside the cart. The carts have a unique IDs/serial numbers to determine the stocking preferences of the carts (FIFO/LIFO).

In an example scenario, a smart item storage cart for produce is provided. The produce cart includes bins for holding produce. The bins have lights (indicators). The cart communicates with a store inventory and/or a DC inventory, as well as picking/stocking software. The cart communicates with store systems to communicate PI info and pick logic. The cart aids users in stocking display cases as well as supply chain management.

In one non-limiting example, an empty item storage cart at a DC is selected. A picker scans the cart identifier and picks to it in a consistent, predetermined patter with an established starting point. The items are loaded onto the cart based on aisle location adjacencies in a destination store. The fully picked (loaded) cart is added to an invoice and loaded onto a truck with the carts stacked up to two carts high. Auto-finalization of the invoice occurs when the truck arrives. Using pick logic for replenishing display shelves, the bin indicators on bins containing items that need to be stocked are lit. The system evaluates sales, markdowns, PI changes, and sends signals to carts to illuminate indicators on bins for items to be stocked onto displays. At the end of the day, the system determines which items are remaining on which carts. The system identifies partially filled carts containing like items for consolidation of cart contents based on item categories and aisle location information (assigned display areas for items). When the carts are empty, the carts are scanned out as empty and returned to the DC for replenishment. When the DC receives the empty carts back, the DC refills the cart with items to be sent back to the store.

In some examples, when the cart is brought to the sales floor, the cart lights up an indicator associated with a bin storing the items that need to be stocked. If a full case needs to be stocked, a full light is illuminated. If a half case is going to be re-stocked, half of a light is illuminated. The cart location is tracked in the store. If the cart location is at the proper place for stocking, the system assumes the items needing stocking at that location were removed from the cart and added to the appropriate item display case/side-counter. The cart system automatically reduces the cart inventory container contents by the number of instances of the items designated for re-stocking. The system triggers a stocking order from backroom once a half case is needed for re-stock.

In other examples, the bin indicator device includes a digital readout of the number of instances of a selected item to stock. The cart can have a robotic propulsion system (self-navigation system) to autonomously move the cart to the proper location in a DC or store for stocking.

In an example scenario, a user scans an orange on the sales floor requesting thirty pounds of oranges for a large display of oranges. The system recognizes the outside-of-PI need for product. The system activates bin indicators on bins containing oranges for use in stocking the large display. In some cases, the carts containing oranges autonomously moves to the area near the display of oranges for utilization in creating/stocking the display.

If a store has multiple partially filled carts containing instances of the same item, the contents of two or more of these carts can be combined/consolidated. In other words, if there are two partially filled carts containing grapes, the contents of the two carts can be combined into a single cart. When the users are finished combining the carts contents, a new invoice is generated for each cart. The new invoices, indicating that one cart has been emptied and the other cart is now full, are assigned to the carts. In another example, a two partially filled item storage bins are combined into a single full item storage bin if both bins contain the same items. The cart inventory is updated to reflect the updated contents of each bin.

An indicator device on a cart flashes or otherwise provides a notification indicating the cart has arrived at a destination (item display area). The indicator notifies the user that the cart has arrived at the appropriate location for restocking an item display.

A smart item storage cart knows the contents of each item storage bin on the cart. In some examples, when a user (picker) fills an item storage bin with produce, the user scans the cart identifier (serial number), the bin identifier, and/or the item identifier. The user loads items into each bin on the cart in a defined order. In some examples, the indicator lights up at the correct bin to be filled during pick operation at the DC. The user knows which items to put in which bin because the bin indicator for the correct bin lights up to indicate which bin the user should fill. The bin indicators light up in sequence as the user fills each bin to ensure the correct bins are filled with the correct items in the correct sequence. When the PI value for a given cart indicates the cart is empty, the system prompts for a manual verification. If a user verifies the cart is empty, the inventory value is confirmed. If the cart is not empty, the user manually updates the contents of the cart.

In one example, an item storage cart includes a location monitor to track cart location. When the cart leaves a temperature-controlled area, such as a truck or storage area, the cart starts a timer to track cart dwell-time. When the cart re-enters a temperature-controlled area, such as a cooler, the timer stops. The cart remains in the temperature-controlled area for a minimum in-cold time before the clock resets indicating it is safe to remove the cart from the temperature-controlled area again.

The smart item storage cart in other examples maintains a database of coefficients relating surface temperature to internal temperature for dwell-time determination to prevent item spoilage. These coefficients can be stored in the item file. This allows for a specific item to have an allowable out-of-cold-chain time, that is tailored to that item. For multiple items on the cart with different dwell-times, the cart is assigned the lowest dwell-time. For example, if oranges can be out of cold chain for one-hundred twenty minutes without risking spoilage, but apples can only be left out for twenty minutes, the maximum dwell-time for the cart is twenty minutes. The cart can remain out of cold chain for as long as the most sensitive item on the cart allows.

The cart can include a thermometer or infrared (IR) temperature reader that detects surface temperature of items on the cart. The sensors read the item temperature directly and/or the sensors can be mounted to a surface of the cart. If thermometers are applied to a metallic part of the cart, or other exposed section where temperature comes down rapidly, (higher coefficient of conductivity than the produce) a ratio of thermal conductivity of the cart structure to the produce in question is utilized to account for the different in temperature change.

In some examples, if the temperature of an item is outside an acceptable range, the indicator or notification component alerts the user that the item is no longer suitable for use/recommends disposal of the item. The cart can provide a specific visual identifier on a bin indicator for non-sellable items due to cold-chain violation. The bins are conceived to have lights indicating occupancy that illuminate in different colors for non-compliant items to-be-discarded. The cart updates central inventory via on board cart communications device so the PI is adjusted automatically. The contents of the bin are removed from available inventory for stocking.

In some examples, a plurality of item storage carts autonomously pre-stage in the proper location for efficient picking/loading of carts at beginning of the stocking shift. The cart contents are already assembled by store aisle location, each cart moves to the proper aisle location to prepare for stocking. The users do not need to retrieve individual carts or determine where items on the cart should be placed within the store. The carts are pre-staged autonomously. Upon completion of stocking, the carts automatically return themselves to the temperature-controlled area.

The cart continuously reports PI and places orders if a stocking order is placed and there are no suitable items available to stock the item displays. The cart adjusts store inventory and/or cart inventory if it determines items on the cart are voided/unsuitable due to cold chain. This triggers an order.

Each bin can include a camera array that captures images of items on the cart. The system uses known dimensions (item data), visual attributes in the item file, image data, item recognition analytics, and image data to estimate bin quantity and maintain accurate PI for each bin/cart. If a single item is spoiled or a portion of the items in a bin is discarded by the user, the system automatically updates the inventory without user intervention. User action is unnecessary for the system to adjust for discarded or non-compliant items removed from the cart.

In an example, the cart communicates with store image recognition software. The image recognition software identifies an absence of apples on an item display for apples. If apples are available on the cart, the cart automatically triggers restocking of the apple display using the apples from the cart. The cart circumvents the central database. A local stocking order is initiated by cart instead of a central inventory system based only on the lack of apples seen on camera and the existence of apples in the cart.

When an item storage cart is fully stocked at the DC, it is transported to a store ready to stock on the sales floor. The forklift channels enable a forklift to easily lift the carts for loading onto a truck. Once loaded onto a truck, the cart removes the contents of the cart from the DC inventory. When the cart arrives at the store, the cart updates the store's inventory to add the contents of the carts. Geofencing around the backroom (stock room) enables the cart to determine when the cart is leaving/entering the backroom. A user scans a cart identifier on the cart to retrieve an invoice for the cart. The invoice data provides an inventory of items on the cart. The invoice data specifies which item is in which bin. For example, a top bin can contain pears and a middle bin can contain apples.

The cart performs self-maintenance in some examples. For example, if the internal temperature measurements generated by temperature sensors on the cart do not match the internal temperature measurements generated by temperature sensors within refrigerated cases, the cart identifies a potential maintenance issue on the cart's sensors. Likewise, if the system is not receiving data from one or more sensors, the system identifies a maintenance issue.
